Ecology Project. Unit 6. What is Ecology?. The study of interactions between organism’s and their environment . What is an Ecosystem?. The living and non-living things in an area. What is a habitat?. The place where an organism lives and provides the needs for that organism.
The study of interactions between organism’s and their environment.
The living and non-living things in an area.
The place where an organism lives and provides the needs for that organism.
The living things in the environment.
The non-living factors that effect living things.
Look around the classroom, name two biotic factors and two abiotic factors.
Select a photo of an ecosystem that has been cut out already.
Glue this photo to a piece of construction paper.
Label the abiotic and biotic factors on your picture.
A certain plant needs moisture, oxygen, carbon dioxide, light and minerals in order to survive. This statement shows that a living organism depends on (abiotic or biotic factors)? Why?
A food chain explains how food ENERGY is transferred between living things in an environment.
In a food chain, you are either the producer or consumer.
All food chains start with the sun. Why?
Producers make their own food.
Consumers eat other living things, like other animals or plants.
A herbivore only eats plants.
A carnivore eat only animals.
An omnivore eats both plants and animals.
Decomposers break down dead plants and animals.
After your food chain is complete, in your NB, write to explain where your living things from your food chain get their energy from.
You will investigate food chains by getting a specific part of a food chain.
You are going to be given a card. You then have to find the other members in your food chain and put yourself in order.
When you are done, raise your hands.
Use the following statement and fill in the blanks.
“I ate bacon for breakfast, my energy came from a pig, that energy came from _________ and that energy came from _________ and that energy came from the sun.”
A food web is a complex arrangement of food chains.
The direction of the arrow points in the direction of energy transfer, NOT “what ate what”.
Even if you can’t name these organisms, how can the direction of the arrows tell you where the producers are? Where the herbivores are? Where the omnivores are? Where the carnivores are?
2. Label the following terms – carnivore, herbivore, omnivore, consumer, producer and decomposer
How are omnivores, carnivores and herbivores alike and not alike? Justify. Use your NB.
An energy pyramid shows the amount of energy available in each step of a food chain.
The steps of an energy pyramid are called trophic levels.
A trophic level is the position occupied by an organism in a food chain.
1st Trophic Level: Producers
2nd Trophic Level: Primary Consumers
3rd Trophic Level: Secondary Consumers
4th Trophic Level: Tertiary Consumers
Why must an energy pyramid start with a producer?
The greatest amount of energy is found in the base of the pyramid.
The least amount of energy is found at the top of the pyramid.
What does the shape of an energy pyramid tell you about how the amounts of available energy change from one level to the next?
Which level of an energy pyramid contains the most energy? Why?
What special structure does a plant have to make them a producer?
A transport tissue with the basic function to transport water from the roots throughout the plant.
Xylem is found in the roots and stems of plants and is like a tiny tube.
The “strings” in celery are xylem tubes.
How is a xylem in a plant similar to a circulatory system in a human?
A process where plants make their own food.
Photosynthesis occurs in the leaves of plants.
Can you name the structure in a leaf that is responsible for photosynthesis?
Carbon Dioxide CO2
Glucose – chemical energy in the form of a sugar
Formula for Photosynthesis:
6CO2 + 6H2O +light C6H12O6 + 6O2
Write to complete this sentence:
During photosynthesis, _________ energy is converted into __________ energy?
Add the chemical reaction for photosynthesis to your poster project. Create a simple sketch on your poster to help you remember what “goes into” and “out of” a plant during photosynthesis.
What are the products of photosynthesis?
Finish your photosynthesis writing.
Add this question to your journal:
What substances are necessary for photosynthesis to occur?
What is necessary to “power” this reaction?
Tropism is an organism, or a part of an organism’s response of turning or bending movement toward or away from an external stimulus, such as light, heat or gravity.
Phototropism causes a plant’s stems and leaves to grow toward the light.
Geotropism is the downward growth of roots.
Gravity helps plants grow in the proper position to seek light.
What forces are acting on these plants in the animations?
If you plant a seed upside down will it still grow properly? How do you know?
Predict in your journal what abiotic and biotic factors you will find.
Predict in your journal what plants and animals you might find outside.
You will need to observe food chains in your ecosystem.
Record in your journal the abiotic and biotic factors you see.
Record the producers, consumers and decomposers you see.
Create a food chain to represent the flow of energy in your ecosystem.
What is the source of all food in your ecosystem and what process produced that food?
Living things have bodies that are adapted for the places they live and the things they do.
Adaptations can be structural or behavioral.
How do these structural adaptations help an organism survive?
What external (physical) adaptations allow organisms to survive in a lake?
You and a partner will demonstrate how the human hand is adapted for the actions it performs.
How can a beneficial adaptation be harmful to an organism if the environment changes?
